Commercial Hot Water Supply

Commercial Hot Water Supply

A constant supply of affordable hot water

As a specialised air-water heat pump solution supplier, Energy Alternatives is in a market leading position and proud to introduce the latest innovation HPWH (Heat Pump Water Heating) technology for commercial and industrial applications in NZ.

Commercial water heating provides an economy of scale which allows energy efficient and renewable energy solutions to be more financially attractive than what is typically achievable in the residential sector. Successfully delivering on a commercial project, however, requires a detailed understanding of the how the performance of the systems is impacted by ever-changing environmental conditions. Understanding the fundamental drivers of performance of these technologies is key to the integration into a system which delivers the required energy service, and energy savings.

At the core of Energy Alternatives is heat-pump water heating. Heat-pump technology has been used for many years to provide space heating throughout New Zealand. A more recent application of this technology is water heating. Heat-pump water heaters have only slowly gained market share in New Zealand, despite the Oceanic Climate being particularly well suited for the technology.

Energy Alternatives, in conjunction with our partners, is committed to developing the potential of heat-pump water heating technology in New Zealand. We recognize that the technology requires products which are application specific in their design, rather than a ‘one design suits all’ approach. This allows the performance of each unit to be optimized for the application, and a number of independently monitored systems across New Zealand is proving the performance and durability these systems.

With capacity from 5 – 250KW, the Aquarian Commercial Range is ideally suited for most commercial and industrial water heating projects offering:

Water heating to 60°C for storage

Space heating at 45°C

Heat service HW at 45°C to meet peak load, functioning as an ‘instantaneous’ water heater, when storage tank is exhausted

Extends the storage capacity of a tank, through use of the single pass mode. Eg a 2000L tank at 60°C can be extended by 500L per hour with a 15kW system. This will meet the demand equivalent to a 3000L tank without the extra capital cost / storage losses. This is particularly useful where the demand has significant weekly or seasonal peaks, but the rest of the time is much lower.
